In his latest autobiography, Ferguson said he fell out with Beckham after criticising his performance during an FA Cup defeat by Arsenal in 2003.

"The minute a Manchester United player thought he was bigger than the manager, he had to go," he wrote. "David thought he was bigger than Alex Ferguson.
"That was the death knell for him."
Ferguson also said he had concerns about Beckham's celebrity lifestyle, following the player's marriage to Victoria Adams, a member of the pop group the Spice Girls.

"David was the only player I managed who chose to be famous, who made it his mission to be known outside the game," wrote Ferguson. "I felt uncomfortable with the celebrity aspect of his life."
In a press conference on Tuesday to launch his book, Ferguson added: "He fell in love with Victoria - that changed everything."
But he also praised Beckham for his contribution to United's success and called him an "icon to every kid in the world

Beckham, who won six Premier League titles, two FA Cups and one Champions League crown during his United career, was eventually sold to Real Madrid for £25m in the summer of 2003, before moving to the United States to play for LA Galaxy.
